excellent stock shots of a variety of people using the telephone;
dialing telephone long distance; smoking a cigarette;
introduction of operator toll dialing: new equipment which reduces the time it takes for long distance call to go through
very detailed explanation of how automatic switching equipment works; and how telephone calls are routed through different cities;
Bell Labs people doing research;
manufacture and assembly of Western Electric electronic telephone switches; installation of giant banks of switches;
Nice aerial view of a city - icons of operators ("girls") pop up on the screen indicating how things were before direct lines (toll calls). "Girl" A connects with Girl B, etc... By the end, icons of operators are all over the screen atop the aerial view of the city.
worth noting: some excellent sounds of pushbutton phones with melodramatic music laid over them.

At the end there is even a good shot of an accoustic lens.
Subject: As soon as the operator presses the proper keys, it happens! Just like that!
Part of the explanaton about how the new technology worked includes a demonstration with sound of the then new "multi-frequency" or MF tone senders.
Different and more pleasant sounding than the "touch-tones" used by our phones today, MF tones were used internally by the switching network. Though they're now nearly extinct, MF tones were considered by phone phreaks to be among the most beautiful sounds heard on the old network.
The film also has some great shots of toll opeartors processing calls and of the original Western Electric #4 Crossbar switches being built and installed.
The climax of the film comes after the old, manual method of calling long distance is compared with the new operator toll dialing when the narrator proclaims: "As soon as the opeartor presses the proper keys, it happens! Just like that!".
Subject: We've got a toll on you!
Ripe with old fashioned operators taking down calls and connecting them (but not saying "surely" :( ) and with a whiz bang commentary, this sure is a lot of fun. And if you, just like I did, noticed the toness corrosponding to the numbers are different then they were when they were introduced, well here's a flip book with city codes for you! Reccomended!
Subject: A must watch
This is attributed to the new feature of operator assisted toll dialing.
The steps an operator would have to perform for each call is shown.
Main step being the use of a key set to help route the call using system tones.
An animation then shows both the old and new method of call routing so we can compare them.
A phone company switch is shown and the tones generated by the operator key presses are played back.
Note: these tones were later exploited by phone technology enthusiasts called phone phreaks.
A further explination of how the call routing is performed by the equipment is provided.
Bell Labs and Western Electric are shown as developer and manufacturer of the equipment.
We are told of the demand for more trained professionals and that someday toll calls will go through just like local calls.
A reference is made to the unknown future uses of such equipment and the bell system goal of improving service/cost. I recommend watching this film.
